   Crazy link man.

   Anyway, anybody with the right radio hardware

   and a little Linux box with OpenBTS and maybe

   asterisks (or other software setup depending)

   can roll something like this out...

   Last i checked it didn’t support 3G but the phones can

   be tricked into switching down to 2G unencrypted

   if you blast a strong enough signal. Newer phones maybe

   more resilient?

   I don’t know how much more advanced the commercial

   stingrays are over the best roll-your-own...

   There are android apps that do IMSI catcher detection,

   but they have some issues.
